Water Cycle and Weather Systems Flashcards
Grade 5 · Science · Flashcards
Review the stages of the water cycle and key concepts in weather systems with these study cards.
Flashcards
- Water Cycle
- The continuous movement of water through Earth's atmosphere, surface, and underground systems. Also called the hydrological cycle.
- Evaporation
- Solar energy converts liquid water at Earth's surface into water vapor that rises into the atmosphere.
- Condensation
- Water vapor cools as it rises, converting back into liquid droplets that form clouds and fog.
- Precipitation
- Water released from clouds and falling to Earth as rain, snow, sleet, or hail.
- Runoff
- Water that flows over land into streams and rivers after precipitation, eventually returning to the ocean.
- Transpiration
- Plants release water vapor through leaf pores (stomata). Combined with evaporation, this is called evapotranspiration.
- Groundwater
- Water that soaks into soil and collects in underground reservoirs (aquifers); can feed springs and wells.
- Weather
- The short-term state of the atmosphere (temperature, precipitation, wind) in a specific location at a specific time.
- Climate
- The long-term average weather pattern of a region, typically measured over 30 or more years.
- Air Mass
- A large body of air with similar temperature and moisture content throughout, covering thousands of square kilometers.
- Cold Front
- The leading edge of a cold air mass pushing into warmer air; brings rapid weather changes, storms, and cooler temperatures.
- Warm Front
- Where warm air gradually advances over cold air; typically brings steady, widespread rain or drizzle.
- Humidity
- The amount of water vapor present in the air; high humidity makes air feel warm and sticky.
